APC by Schneider Electric APDU1335T3H Rack PDU Temperature (Qty 3) and Humidity Sensor Kit
Overview
The APDU1335T3H is a multi-point environmental sensor bundle designed for APC Netshelter rack PDUs, giving you three temperature probes and one humidity sensor in a single kit. If you are managing thermal conditions across a rack or row of equipment, deploying three temperature sensors simultaneously lets you map hot-spot gradients — top, middle, and bottom of the enclosure — rather than relying on a single reference point that can miss localized heat buildup. The sensors ship in a compact, low-profile form factor (50 mm wide × 100 mm deep × 8 mm tall) that fits inside a populated rack without consuming a rack unit or blocking airflow paths.
Key Features
- Three-sensor temperature coverage: A single kit provisions three discrete temperature measurement points. In a dense rack, a single probe at the top can miss inlet temperatures rising at mid-rack — three probes give you the gradient data your cooling decisions actually need.
- Integrated humidity monitoring: The included humidity sensor detects moisture conditions that temperature alone won't flag. Humidity excursions often precede condensation failures in environments with variable CRAC unit performance.
- Low-profile enclosure (8 mm tall): At 8 mm tall, these sensors mount flush against cable management or PDU rails without obstructing adjacent equipment or airflow baffles.
- RoHS, REACH, and WEEE compliant: Mercury-free and free of substances of very high concern (SVHC) — relevant for enterprise procurement teams with materials compliance requirements or EU e-waste obligations.
- Lightweight deployment (167 g packaged): The entire kit ships at 167 g, so adding environmental monitoring to an existing rack requires no structural recalculation or weight budget review.
Integration and Compatibility
The APDU1335T3H is designed for use with APC Netshelter rack PDUs that support environmental sensor inputs. Verify your specific PDU model's sensor port count and connector type before ordering — some PDU variants support a limited number of sensor daisy-chains, and deploying all three temperature probes plus the humidity unit may require a sensor hub or a PDU with multiple sensor ports. Confirm compatibility with your rack PDU line and review the environmental monitoring integration requirements for your data center management platform.

Frequently Asked Questions
Q: Is the APDU1335T3H compatible with all APC Netshelter rack PDUs?
A: The APDU1335T3H is designed for APC Netshelter rack PDUs that include environmental sensor ports. Not all Netshelter PDU models support the same number of sensor connections. Verify your PDU model's sensor port count and supported sensor types before deploying all four sensors simultaneously.
Q: What environmental parameters does the APDU1335T3H monitor?
A: The kit monitors temperature at three discrete points and humidity at one point. No additional parameters (such as airflow or leak detection) are documented for this kit.
Q: Is the APDU1335T3H RoHS compliant?
A: Yes. The APDU1335T3H carries RoHS, REACH, and WEEE compliance certifications and is documented as free of mercury and substances of very high concern (SVHC).
Q: How large are the sensors in the APDU1335T3H kit?
A: Each sensor measures 50 mm wide × 100 mm deep × 8 mm tall — a low-profile form factor designed to fit inside a populated rack without consuming rack unit space.
Q: Does the APDU1335T3H require a separate power supply?
A: No dedicated power supply data is documented for this kit. Environmental sensors of this type typically draw power through the PDU sensor port. Confirm power delivery with your specific Netshelter PDU model's documentation.
The APDU1335T3H is the kit I recommend when a customer wants multi-point thermal coverage in a single procurement line item. The three-probe temperature setup is the practical differentiator here — most basic PDU sensor accessories give you one temperature reference point, which is fine for a lightly loaded rack but insufficient once you start pushing 60–70% of rated PDU capacity and need to confirm that mid-rack inlet temps aren't climbing while the top-of-rack sensor reads normal.
Technical Highlights:
- Three discrete temperature probes: Lets you instrument top, middle, and bottom of a rack in one order. Gradient data across the 8 mm low-profile sensors is far more actionable than a single-point average for DCIM threshold alerting.
- Humidity sensor inclusion: Catches what temperature monitoring misses — a humidity spike often signals a cooling unit issue before temperatures climb enough to trigger an alert.
- RoHS/REACH/WEEE certification: The mercury-free, SVHC-free compliance documentation simplifies procurement for enterprise customers with EU materials compliance requirements or internal sustainability reporting obligations.
Deployment Considerations:
- Confirm your target Netshelter PDU model's sensor port count before assuming you can connect all four sensors (three temperature plus one humidity) simultaneously — some PDU variants have limited sensor chains.
- The 8 mm sensor height fits flush in most rack configurations, but route sensor cables through dedicated cable management channels; loose sensor leads draped across PDU outlets can partially block plug access.
This kit is best suited for high-density colocation racks or edge data rooms where operators need thermal gradient data across the full rack height — not just a single top-of-rack reference — and where humidity incidents need early detection before they affect uptime SLAs.
